Bunion braces are effective for patients with mild to moderate bunions, while for patients with severe bunions, the results are usually poor, as follows: First, there are effects: Patients with mild and moderate bunions who insist on using bunion braces can continue to act on the bunion joint to correct the bunion deformity, and although complete correction is not guaranteed, it can still significantly relieve the painful symptoms caused by the bunion. Second, no effect: severe bunion deformity cannot improve the clinical symptoms even with comprehensive treatment such as bunion braces. Most of them need surgical treatment to alleviate the clinical symptoms of bunion and correct the deformity of lower limbs through osteotomy, release and removal of bunions. Therefore, there is a certain range of treatment for bunion braces, and not all bunion patients can be corrected with braces.
